   Sammanfattning : During the last years, nanostructured ceramics have been favored for use in the industry due to their beneficial properties. For example, calcium phosphate ceramics with their biocompatible and bioactive characteristics are beneficial in biomedicine. LÄS MER

5. 4. Hydrogen in nano-sized metals : Diffusion and hysteresis effects

   Författare :Wen Huang; Björgvin Hjörvarsson; Max Wolff; Gavin Walker; Uppsala universitet; []
   Nyckelord :Hydrogen; diffusion; hysteresis; optical technique; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

   Sammanfattning : Metal hydrides can be used as hydrogen storage materials for fuel cells and batteries, and as sensors for detecting hydrogen gas. The use of metal hydrides for hydrogen storage can be hindered by poor kinetics and low capacity. Moreover, poor sensitivity, long recovery and response time, limit the applications of metal hydrides as hydrogen sensors. LÄS MER

7. 5. Pharmacometric Characterization of Postprandial Responses and Taste Perception in Individuals with Obesity

   Författare :Jennifer Leohr; Maria Kjellsson; Andrew Hooker; Martin Adiels; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacometrics; mechanism-based; categorical modeling; obesity; triglycerides; glucose homeostasis; taste perception; linked categorical;

   Sammanfattning : Obesity is a major health epidemic worldwide and occurs when long-term excess of energy intake beyond energy utilization leads to an increase in adipose tissue. Energy balance is coordinated by the central nervous system regulation of appetite and adaptive thermogenesis via a complex array of neuropeptides which communicate to the periphery by various circulating measures dictating the utilization of various energy sources such as, carbohydrates, fat, or protein.
